javascript switch(true)

Question

Hi i am trying to handle an ajax json response

here is my code

success: function (j) {     
    switch(true)
    {
        case (j.choice1):

                


        

Answer 1

It works for me:

var a = 0, b = true;
    
switch(true) {
    case a:
        console.log('a');
        break;
    case b:
        console.log('b');
        break;
}

However, the case labels must be equal to true, not jut implicitly true.
Also, only the first case that evaluates to true will execute.
